Talking to myself again probably: I don't think the default install of LiveJournal as we distribute it should require the qbufferd running, or do any query buffering at all. I doubt anybody will be getting as much traffic as livejournal.com does. I think I'll make a new $LJ::BUFFER_QUERIES option, then change query_buffer_add/_flush to respect it. Pretty easy change. Then we can leave that out of the INSTALL file. I figure we can have a sepate part of the documentation that talks about tuning the installation for high load, which'll mention the use of qbufferd.
